Modular design and customisable options

FSP Hydro PSUs are 100% modular which allows customer to use only the cables required to power all installed components. This not only makes the install clean and tidy but also helps to increase system airflow which could be blocked with used non-modular cables. FAP have also made it possible to customise the PSU with alternative stickers of the side of the PSU. If you are interested in making the PSU match the internal colour scheme of the system then two red and green theme stickers are available to allow for this.

High quality Japanese capacitors

FSP have chosen to utilise Japanese capacitors. The main reason for this is to give the PSU longevity and reliability as Japanese capacitors are renowned for being the best available.

FSP have also introduced a new heat dissipation design that conducts heat through a thermal pad on the bottom of the power supply which transforms the whole PSU casing into a heat-sink.

Noise Levels

The chart to the left shows the respective noise level depending on the load of the PSU. As you can see anything below a 25% load will stop the fan from spinning meaning the PSU will be 100% silent which is excellent news for customers wanting the quietest option. When the load increases so does the fan speed. The PSUs are designed to stay at a low noise level for loads under 50%. If the fan remains below 1000 RPM then we would consider it to be extremely quiet.

Plethora of cabling options

All power cables supplied with the Hydro G power supply are of the "ribbon cable" design. This makes the installation extremely tidy and easy to work with. Gamers will be happy to note that PCIe connectors for multiple graphics cards are available. 650W version can accommodate two graphics, while the 750 and 850W PSUs support up to three graphics. Numerous SATA and Molex power connectors are also available. See the specifications cable below for exact details.

A 5-star PSU, but it came with an EU mains lead!

Tim Bierman, 26th May 2017

As a PSU it seems to be brilliant. It replaced an Elan Vital 400W and it's not a very power-hungry PC, so even at 100% CPU load the fan isn't running (or is running too slowly to hear) and the case is cool. A big improvement.

It doesn't matter to me that I now have yet another EU-style mains lead to join the pile, since I already had a UK lead on the PC. Anyone fitting it to a new PSU might get stuck without a lead, though.

Excellent service as usual

This was ordered to replace an ageing Zalman power supply that was getting a bit noisy. After replacing the power supply my server is now as near silent as can be with only a faint hum of the disks rotating.

I now just need to save up and replace the disks with SSD's for a completely silent server.
